The accident happened at the corner of Groathill Road North and Wester Drylaw Avenue, Edinburgh, at about 12:30pm yesterday. She was taken to the city’s Sick Kids’ hospital with abdominal injuries.
Lothian and Borders Police said the driver of the Renault Clio stopped at the scene and is helping them with their inquiries.
Elsewhere in the capital, at about the same time, a seven-year-old boy suffered a broken leg after being clipped by a car.
The child and his brother were standing on a traffic island in Gilmerton Road, at about 12:40pm, when a silver or gold car hit him but did not stop.
He was taken to the same hospital.
Chief inspector Alwyn Bell, of Lothian and Borders Police, said yesterday: “It may well be the driver is not aware that anything happened so we would appeal for anyone who may have been driving in Gilmerton Road this lunchtime, and who may have seen the boys on the traffic island, to get in touch.
“We’re also keen to hear from anyone else who was in the area, and who may have seen the vehicle involved, or have information about exactly what happened, to contact us.”
